TdxRectWrapper.OnChanging Event
In This Article
Occurs when coordinates of a rectangle maintained by the TdxRectWrapper object are about to be changed.
#Declaration
Delphi
property OnChanging: TdxRectChangingEvent read; write;
#Remarks
Write an OnChanging event handler to change coordinates as your needs dictate. For instance, the following code allows users to avoid changing the left coordinate:
if [rsLeft] in Sides then
Values[rsLeft] := dxRectWrapper1.Left;
